教程2：
今天重裝了Opencv3.20 和Opencv3.2.0conbtrib，將安裝日志記錄如下：
1. 查詢自己的Opencv版本 ??pkg-config --modversion opencv??
2. 下載??Opencv3.2.0 和Opencv contrib3.2.0?? 對于opencv3.2.0 ???https://pan.baidu.com/s/1bp03gab??? 對于Opencv3.2.0 contrib
3. 卸載當(dāng)前的Opencv ,進(jìn)入安裝的build目錄,執(zhí)行 ??sudo make uninstall?? ，然后??cd ..?? 執(zhí)行??rm -rf build??
4. 清理/usr中所有的opencv相關(guān)選項(xiàng) ??rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*??
5. 執(zhí)行 ??sudo make -j16?? 和 ??sudo make install?? ， 在make的時候我遇到一個問題就是??fatal error: LAPACKE_H_PATH-NOTFOUND/lapacke.h??: ??No such file or directory #include “LAPACKE_H_PATH-NOTFOUND/lapacke.h??” 原因：未找到lapacke.h文件 ，只需要??sudo apt-get install liblapacke-dev checkinstall??就可以解決繼續(xù)make了。成功后進(jìn)行第5步。
6. ??cd /usr??
7. ??find . -name "*opencv*" | xargs sudo rm -rf??
8. 成功后在終端中打開 /etc/ld.conf.d/opencv.conf 文件，并在最后一行添加 /usr/local/lib，如果沒有這個文件那就新建一個。然后打開 /etc/bash.bashrc 文件，在最后一行中添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/opencv320/lib/pkgconfig
export PKG_CONFIG_PATH
最后. ??sudo ldconfig??生效
備注：最后使用??pkg-config --modversion opencv??查詢版本如果報錯為：
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
則需要運(yùn)行下邊語句：
sudo cp /usr/local/opencv320/lib/pkgconfig/opencv.pc /usr/lib/pkgconfig
